' and securing the wrapper by crimping or bending the ends of thewrapper inward upon themselves whereby the end portions of the articleor package, except at the extreme edges, are exposed to view.

The inventionis especially applicable to what are termed coin packagesin which a pile of coin are secured in a package by suitably crimpingthe projecting ends of the wrapper; which facilitates the handling ofthe coin, the contents being visible at eachend of the package.

One of the objects of the invention is to provide in a machine of thischarabter, an improved form of bending finger or crimper; and also toprovide an improved form of means for controlling the operation of thecrimper whereby it will automatically accommodate its operation to thedifferent diameters of coins.

In the accompanying drawings Figure 1 is a plan view of a portion of amachine embodying my invention. Fig. 2 is a similar view showing a partonly of the mechanism shown in Fig. 1. Fig. 3 shows in end elevation,parts shown in Fig. 1. Fig. 4 is a similar view with the parts indifferent positions. Fig. 5 is a view similar to Fig. 4 but enlarged,with the parts in still another position. Fig.6 shows in perspective thecrimping finger in the operation of crimping a wrapper on a coinpackage, and Fig. 7 is a section taken on the line 77 of Fig. 6.

The coin package denoted generally by 10 is supported between threeparallel rollers 11, 12 and 13;

and. the distance apart of these rollers is made variable to accdmmodatedifferent sized coin, that is different diameters of the coin packages.The roller 11 has a journal 14 at each end by which it is rotatablysupported in hubs 15 but eccentric'therewith. The hubs are arranged tooscillate in bearing portions of upright sup ports'lfi and 17, wherebysuch rotation ofthe hubs Wlll cause a movment bodily of the roller 11.The roller 12 is similarly mounted, having journals 18 at each end thatare rotatable in hubs 19 in eccentric positions. The hubs 19 aresupported to oscillate in the side members 16 and 17, whereby suchmovement of the hubs will cause a movement bodily of the roller 12.

The third roller 13 is movable to and from the rollers 11 and 12 bymeans of journals 20 at each end that are each rot-stably carried by aT-shaped irame 21. The T members are in duplicateat each end of themechanism as shown in Fig. l, and a description of one will answer forboth. This frame 21 has its portion 22 slidable in a guide box 23. Theframe 21 is caused to oscillate by means of a lever 24 pivoted at 25 onthe frame member, (16 and 17,) which lever is swung in one directionfrom a cam member 26, the lever being held against the cam by a spring27 which serves to swing the lever in the other direction. The frame 21is adjustably connected with this lever 24 by means of a nut 28slidable.

in a slot 29 of the member 22; and adjusted therein by means of a screw30 rotated by handle 31. A pin 32 on the nut 28 operates in a slot 33 inthe lever By this means the oscillation of the lever by the cam willserve to reciprocate the frame member 21, (at each end) and thereby theroller 13, moving it forward and from I the rollers 11 and 12. Therollers 11 and 12 may also be given a movement toward and from eachother, as the roller 13 is adjusted, to accommodate for variousdiameters of coin packages, as indicated in Figs 3 and 4.

Y The hub 19 has an arm'35projecting therefrom, between which and oneend of the frame 21 is pivoted a link 36. The hub 15 has an arm 37connected with the opposite portion of the frame 21 by a pivoted link38. By this means the sliding of the frame 21 will rock the hubs 15,

and 19-, and thereby cause the movement bodily of the rollers 11 and 12moving them'toward and irom the roller 13. This will produce a mutualapproaching movement of the three rollers when the frame moves in onedirection, and a mutual receding movement of the rollerawhen the framemoves in the opposite direction.

It will be observed that during one half the revolution ofthe cam 26 itsconcentric portion will engage the le; ver 24 and retain the rollers inthe closed position permitting the operation of the crimping mechanism.-

-. The crimping operation is effected at each end of the V package byduplicate means; each comprising afinger or crimper 40 carried by asleeve 41 that is rotatable on a bent rod 42 and given a slightyieldrble movement thereon, by means of a spring 43 connected between'apin 44 fast on the rod 42, and an arm 45 secured to the I sleeve 41. Thefinger or crimper 40 extending from the sleeve 41 is first bent downwardat 46, and then bent transversely or sidewise at 47. In the operation ofthe finger, it is first swung on the axis of the sleeve 80 that theextremity will entirely clear the projecting.

edge of the wrapper, as indicated in Fig. 5. The crimper is given anendwise movement, as indicated in Figs. 1 and 2, whereby its bentportion 46 will turn crimper to engage the inner face of the wrapper andcomplete the operation of doubling the, wrapper upon ioo itself. Thenext operation is to cause a reverse swing of the crimper on the axis of.the sleeve, to withdraw the extremity of the crimper from engagementwith the wrapper; and thereupon. the crimper is bodily'moved 5 to itsformer position, to permit the removal. of the package and anotherpackage'to be-placed in position for operation. One means forautomatically effecting such operation is shown in the drawing, whereineach .rod 42 is secured to a nut member 48 that is supported .toreciprocate by means ofsleeve portions 49 and 50, slidable. on shafts 51and .52 respectively. These shafts are rotatable in .the side members 16and 17. Between the shafts 51 and 52 is lqcated 'a screw member 53having journals 54at each end eccentrically supported in hubs 55, thatare rotatable in the side members 16 and 17 respectively. The swingingof these hubs will shift the screw shaft 53 into and out of engagementwith thread portions 56 on the nut members 48; whereby the rotation ofthe screw will cause the not members to travel from the positions shownin' full to the position indicatedin broken lines. v i The shaft 51 isrotated by any-suitable means, such as a pulley 57, and serves to drivethe screw shaft 53 by means of friction wheels 58 fast on the shaft-51that will engage friction wheels 59 fast on the screw 53, when thelatter shaft is shifted on its eccentric supportto cause its screwportions83 and 84 to engage the nut portions 56. But uponmovement'of-the shaft out of position of engagement with the nutmember,'the friction wheels will disengage. This shifting of the screwshaft into and out of engaging position is effected at each end of themachine from'the operation of the lever I 24 by means ofconnecting-links 60.and 61, thelatter being pivotedto an arm 62 fast onthe hub member 55.

The rod 42 carrying the crimper 40 is secured to the nut member 48, andwhen the lever 24 is in the position shown in Fig. 3, in whichthe three.rolls 11, 12 "and l3 have been caused to approach and engage the coinpackage,-the nut members beingbrought into engagement with the screw,will cause the crimpe'rs to be advanced as indicatedin Fig. 1 to thebroken line position. But by the time the crimpers have traveled a lsufficient distance to crimp-the wrapper, the lever 24 is released bythe cam and moved upwardby the spring, which will throw the screw 53 outof engagement with v I the nutmembers. At-this stage a coil spring 63-on the shaft 52 between the sleeve 50, that has been compressed ,7during the travel of the sleeves, will react andreturn the nut membersand crimpers to their former positions. This movement is limited byadjustable steps 80' whose threaded bore engages-threaded portions 81and 82. of the shaft 52." a L Means are provided for swinging thecrimper on the axis of the supporting sleeve, upon being advanced by.thenut member and causethewrapper to be doubled -inwagd', .and.,also;for. swinging the fingeriinward or 1 iysssr seithe pp at e-endst e i p sP- n st qmbeter t ei imr r rimped por- .e observed passes around. ahuhtifi r hatis eccentrically pivoted. on a journal 67, projecting fromthe nut mem'- 65 her 48... The extending portion of the rod projects*lloope along the nut member and has its extremity secured to a coilspring 68 fast on the member 48. A link 69 is pivoted between the frame21 and an arm 70. fast on the hub 66; whereby the swinging of the framewill rotate the collar on its eccentric bearing moving the 70 rodoutward from the member 48. This lattermotion will swing the crimper onthe axis of its sleeve and move its transverse arm toward or from theperiphery ofthe projecting portion of the wrapper, as indicated in thepositions of these members shown in Figs, 3 and 7 5 4. By thisarrangement, the adjustment of'the nut connection between the lever 24and the frame 21, vaying the path of movement of the frame 21, will,through the link 69, varythe position'of the transverse arms of thecrimpe'rs. 8O 7 Additional means are provided for swinging each crimperon its axis upon the crimper being advanced to engage the paper, andwhich means will swing the crimper inward or away from the wrapper atthe conclusion of its operation before returning it to its formerposition. A cam member 71 is pivoted on the member 48, at each end andhas an arm 7 2 pivotally connected with a portion of the link member 61,that is made somewhat U-shape. The round portion 73 of the cam membernormally engages the rod 65, swinging the rod on its loop axis on thehub 66, retains the crimper with its extremity offset from the wrapper,as shown in Fig.

. 5. But as the lever 24 moves downward, it first brings the rollersinto engagement with the package and also causes the screw member toengage the nut member and rotate the latter 'through the frictiondriving wheels. During this operation, the flat portion 74 of, theeccentric 71 permits thespring 68 to swing the rod 65 to the positionsshownin Figs. Sand .4 thereby swinging the crimper to bringitsiextremityintoengagement with the inner face of the crimping portion of thevwrapper, to complete the crimping operation But upon the returnstroke-of the lever 24, the cam 71 will first swing and rock therod 65to move the crimper arms away from" the paper, before the screw memberisdisengaged from thenut members 48 permitting the I spring 63 to return.the nut members to their former position.

Adjustment for different lengths of packages is pros vided for by meansof theshiftable stopsBOL: At'each release of the; nut members 48 fromthe screw. portions 83 and 84 of the member 53, the spring.63"will movethe nut members in opposite directions,.until they engage the stops 80.At each engagement, of the nut members with the said screw portion theywill advance l. 1 5 a certain distance that is constant,. that'isfora'lccrta in number of threads. This distance will be fronrthea'adjustedlposition of the stops toward each other, and therefore thisadjustment of the stops will determine the range of operative positionsof the crimpers. Mov- 7 ism organized and timed to move the fingerbodily-toward i the end of the package and swing the end portion of thearm outward to crimp the wrapper, to next swing the arm in the reversedirection bringing its end away from the crimped portion, and to nextcause a return movement of the finger to its former position. l
